Question

I want to open up a new view with the identifier AddSourceViewController when a button is clicked. I’m using the following code to do so:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"AddSourceViewController"];
[vc setModalPresentationStyle:UIModalPresentationFullScreen];
[self presentModalViewController:vc animated:YES];

When used in viewDidLoad on an initial view, this code works perfectly and opens up the additional view. However, I have added an IBAction to a button on the initial view and when I add the above code to attempt to open the new view on button click, I just get a Thread 1: breakpoint 5.1 6.1. How can I get this to work on the button action?

EDIT: Better error information below.

Answer 1

Do you have a breakpoint set for your action method? Look on the left side next to the code of this method, to see if there is a blue arrow pointing towards the code.
